Bacterial identification plays an imperative role in pathology, enabling the diagnosis and treatment of many diseases abundant within the human population. Samples from biological tissues as well as artificial reservoirs, are frequently utilised for analysis in order to detect the presence of bacteria. These may be either normal flora, opportunistic pathogens or invasive microorganisms, from which analysis can deduce their role in disease states. The inaugural step in the process of bacterial identification is the culturing of the sample followed by primary isolation, and hence is limited by the fact that the organisms in question must be capable of growth of agar. Procedures for identification are largely dependant on phenotypic analysis, including colony morphology and cellular characteristics. One such defining element of bacterial identification is the Gram stain, which is critical knowledge for classification and the subsequent implementation of antibiotic treatment plans. Furthermore, selective and differential media, and in some cases, Microbacts may be utilised. These provide information as to the biochemical nature and metabolic capabilities of the microorganisms being examined, and are vital tools in bacterial identification. Pathogens detected can additionally be tested in vitro for their antimicrobial sensitivities through culture with various antibiotic discs, in order to support classification and suggest possibilities for suppression in vivo
